I have my home server apps configured with NGINX proxy manager and DuckDNS to access remotely, but about three weeks ago DuckDNS URLs stopped working on my home network. I can access 192.168.XXX.XXX:1234 on the home network but myapp.duckdns.org times out.

It DOES work as expected using a VPN or on mobile data.

Any ideas as to what’s going on?

EDIT: I kind-of sort-of got a workaround working using pi-hole “local DNS” feature to point the duckdns URL to NGINX. Didn’t work

EDIT 2: Disabling the router’s firewall completely seems to have fixed it. Still trying to figure out the exact setting that did it. I will update this post if I can.

    Sometimes DuckDNS goes down partially, their servers breaking for about a week is why I purchased a domain and now host via Cloudflare.

    Edit: One of my DuckDNS domains works internally, so at least it’s not a systemwide issue. Perhaps one of their relays…
